The KM29U128 is a 16M(16,777,216)x8bit NAND Flash Memory
with a spare 512K(524,288)x8bit. Its NAND cell provides
the most cost-effective solution for the solid state mass storage
market. A program operation programs the 528-byte page in
typically 200ms and an erase operation can be performed in typically
2ms on a 16K-byte block. Data in the page can be read
out at 50ns cycle time per byte. The I/O pins serve as the ports
for address and data input/output as well as command inputs.
The on-chip write controller automates all program and erase
functions including pulse repetition, where required, and internal
verify and margining of data. Even the write-intensive systems
can take advantage of the KM29U128¢s extended
reliability of 1,000,000 program/erase cycles by providing either
ECC(Error Correcting Code) or real time mapping-out algorithm.
These algorithms have been implemented in many mass
storage applications and also the spare 16 bytes of a page
combined with the other 512 bytes can be utilized by systemlevel
ECC.
The KM29U128 is an optimum solution for large nonvolatile
storage applications such as solid state file storage, digital
voice recorder, digital still camera and other portable applications
requiring non-volatility.
